QRServ - HTTP File Transfer
What it does
• QRServ creates a tiny, on‑demand HTTP server on your device.
• Pick any file(s) and the app serves them over an unused port.
• Other devices on the same network can fetch the files simply by scanning a QR code or entering the shown URL.
Network requirements
• Both devices must share a local network (Wi‑Fi, hotspot, tethering—no mobile data).
• VPNs work if they route local traffic correctly.
Key features
1. QR‑code shortcuts
• Tap the code → a tooltip shows the download URL.
• Long‑press the code → copy the full URL to the clipboard.
2. Seamless sharing
• Add files directly from the Android sharesheet.
• Multi‑file selection is bundled into a ZIP archive.
• Long‑press the generated ZIP name to see the original file list.
3. Direct‑Access Mode (DAM)
• Bypasses the app cache for large files, reading straight from internal storage.
• Available on Android 10‑ and earlier via the Play Store; Android 11+ users must install the GitHub build (uninstall the Play Store version first).
• Supports only single‑file selection; toggle the mode in Settings.
4. Dynamic file management
• Remove files from the list at any time.
• (With DAM) automatically detect changes to the selected file.
5. Customizable download link
• Show or hide the filename in the URL path – long‑press the share button to switch.
6. Real‑time notifications
• Get a pop‑up when a client requests a file and when the transfer completes, including the requester’s IP address.
7. Port flexibility
• The server binds to a random free port or a user‑specified one.
8. Multilingual support
• English, French, German, Hungarian, Italian, Polish, Portuguese, Spanish, Russian, Turkish, Persian, Hebrew.
Permissions used
• android.permission.INTERNET – discovers network interfaces and opens the listening port.
• android.permission.READ_EXTERNAL_STORAGE – read‑only access to internal, SD‑card, and USB‑mass‑storage files.
Open source
• QRServ’s code is freely available on GitHub: https://github.com/uintdev/qrserv
Just scan, tap, and go
• Start sharing files instantly, without cables or cloud services.
